Could be one App that is synchronising data to the tablet.
Do factory reset.
Remove the memory card
don't use any apps
and monitor the storage space used. (if the internal memory is still getting low so the tablet need to reinstall the firmware)
Make sure you don't setup DropBox account to see what will happen.
after this try one app at a time to see which app is eating the storage.
final option is to do reinstall of the stock firmware again using Odin.
